Mill Operations & Industrial Engineering
Sets a safe replacement interval for carbon-fibre rapier tapes: bending strain over the drive wheel, the life factor that strain implies, cycles to failure, cycles accumulated per week and the weeks and picks remaining before replacement.

Mill Operations & Industrial Engineering
Assesses cavitation and seal failure risk on high-temperature dyeing pumps: liquor vapour pressure by Antoine, net positive suction head available, the margin over what the pump requires, the highest safe liquor temperature and the suction pressure a zero margin would need.
Calculator
Mill Operations & Industrial Engineering
Exposes hidden downtime in rotary printing: screen setup and washdown time driven by colour count, actual printing time, total job time, the productive share of it, effective speed across the whole job and the run length at which printing finally outweighs setup.
Calculator
Factory Physics & Assembly Logistics
Converts pleat geometry into fabric demand: take-up ratio from fold depth and visible width, the flat width needed for a finished panel, pleat count across it, and the extra fabric the pleating consumes.
Calculator
Industrial Engineering, Time & Motion
Converts completed bundle tickets into operator earnings: pieces completed, standard minutes earned, shift efficiency, base piece-rate pay, efficiency bonus above the threshold, the payable amount against the guaranteed wage and the effective hourly rate.
Calculator
Industrial Engineering, Time & Motion
Derives a PF&D allowance from the physical work rather than a flat rate: fabric mass handled per cycle, fatigue allowance from that mass, a reach penalty beyond the comfortable envelope, the total allowance, allowed time and the minutes it consumes per shift.
Calculator
Mill Operations & Industrial Engineering
Builds a ratio pack from retail size demand: garments of each size per master carton by largest remainder allocation, the largest deviation from the demand curve, cartons required for the order and the biggest size overage it creates.
Calculator
Factory Physics & Assembly Logistics
Projects operator learning on a Wright curve: cycle time at the current piece count, efficiency against standard, the cumulative pieces needed to reach the target SMV and how many working days that represents.
Calculator
Industrial Engineering, Time & Motion
Splits a sewing cycle into machine and handling time: actual stitching time from seam length and effective machine speed, total cycle, needle-time and handling shares, and the gain available from doubling machine speed against shaving a tenth off handling.
Calculator
Factory Physics & Assembly Logistics
Balances needle heating against cooling to estimate steady needle temperature, the margin before a synthetic thread fuses, and the sewing speed at which that margin runs out.
